Special Tools

For equivalent regional tools refer to Special Tools .

1. Clean the sealing surfaces.

Note: Ensure that the cylinder head and the cylinder block sealing surfaces are clear of oil, grease and old gasket material.

2. Inspect the flatness of cylinder head and cylinder block sealing surfaces.



3. Install EN-301 measurement bridge  (2) in compound with GE-571-B dial  (1).




Note: The largest measured piston overhang value is determining for the choice of the cylinder head gasket.

4. Measure the piston overhang and compare with the identification on the cylinder head gasket (1).

4.1.	Piston overhang 0.230 mm - 0.296 mm (0.0091 in - 0.0117 in), choose cylinder head gasket with identification A.

4.2.	Piston overhang 0.297 mm - 0.362 mm (0.0117 in - 0.0142 in), choose cylinder head gasket with identification B.

4.3.	Piston overhang 0.363 mm - 0.429 mm (0.0143 in - 0.0169 in), choose cylinder head gasket with identification C.





Note: Mind the guide sleeves.

5. Install a NEW cylinder head gasket (3).
6. Install the cylinder head (2).

8. Tighten the 10 cylinder head bolts in a sequence as shown in three passes:

8.1.	First pass in sequence to 50 N·m (37 lb ft).

8.2.	Second pass in sequence to an additional 90°, using the EN-470-B wrench .

8.3.	Third pass in sequence to an additional 90°, using the EN-470-B wrench .
